IMPROVEMENT INIHVDRANTS.

Specification forming part'of Letters Patent No. 1 77.550, dated May 16, 1876; application filed March 18, 1876. V

Toall whom it may concern I Be it known that I, JOHN PENNYcooK, of

Chicago, county oi'Oook, State of Illinois, have invented certain Improvements in Hydrants, -of which the following is a specification:

t In the drawings, Figure 1 represents a full view of the hydrant. section of it; Fig. 3, atransverse section of top part through the outlets and Fig. 4, a top View of the base part, cover removed.

In Fig. 1, as above stated, the hydrant is represented in full view, the stem A embracing I the base part B for the induction, and the top .part G for eduction of the water-circuit.- The base part B is a casing, with a circular openpressure of the water-column. This main valve carries, on the rear of the disk, behind the seat, a segmental oogged prolongation or cam, G, which turns in a radial direction around its axle h. The cam G gears to the convolutionsofan endless screw or worm, H, on the lower part of a rod, 1, projecting from the top part to the outside of the-hydrantste'm, straight down into the base part, terminating in a shoulder, L, beneaththe lug a, as shown in Fig. 2. The upper end of said rodI, which is coupled tothe lower part at b, is guided through an incasing, K, down the side of the top part of the hydrant, and is thereby protected from exposure, said casing acting as a non conductor against changing temperature. The-bearin gs of the valve-axle are playing in journal-boxes 0 0, located and fastened ;on both sides of the surface of the base part below the level line of the gears G and H, purposely so arranged and constructed, in combination with the shoulder L beneath the lug a, as to prevent the valve from throwing 011' and out its resting-seat. At the center of-v the inclined bottom of the base part is located a hinged drain-valve, M, hearing abalance-arm, d, on one side, in an obtuse uprightposition, placed in the traveling way Fig. 2 is a longitudinal of the main valve, and coming so in tangible 7 contact opens its port, relieving the stem from the contents out to exit. A cover, N,

incases the whole surface, and fastened hermetically on the top of base part, carrying a stuffing-box, f, inside, on the proper place, through which the lower end of the rod I passes to its termination. Theother end of the base part is provided with a neck, 1?, in which the stem A of the hydrant is properly inserted,

and secured by fastening-rods g g from the circuit from the base up through the stem, and

pours out a constant powerful stream, regulated by two eduction-valves, V V, independently situated and worked each from the other. I

These valves are similar in construction, and worked by endless screws, as stated by the description of the main valve. .The shellT covers the top part, in which suitable stuffingboxes, q q, for the valve-rods are applied.

The operation of the hydrant will be fully understood'in the illustration at Fig. 2, which represents a sectional view of my invention, showing all-the interior arrangements, as before explained. Turning the rod 1, the endless screw H at the lower end of said rod, geared to the segmental cam G of the main valve F, turns the valve around the bearings h, out from its seat 70, to its full'extent, uninterrupted in a radial direction, into the casing N, released simultaneously from the pressure of the main. The water-column passes now by a clear way into the receiving-chamber B, closing atthe same time by its force the drain or waste valve M down in its seat, to prevent the water from escape, and through the stem A up to the top, lodging against the valves V V ofthe twoway outlets. Drawing these "alves open from their respective seats, the compressed column of water flows out through the angular discharge-nozzles. To shut 0d the supply from the main, the rod I has to be worked in opposite direction. The valve F, turned then with same radial motion simultaneouslywdown in its seat, opens hereby gradually the drain-valve M, to relieve the stem from its contents.

Having thus describcd'my invention fully in the foregoing specification, I claim as new and desire to secure by Letters Patent of the United States- 1. The disk-valve E, segmental camG,;and relative center bearings h h, in one piece, said bearings fastened on the surface of the base part, as shown and described, for the purpose set forth.

2. The coupled rod I, guided in its upper part at K, passing down and fastened in the 7 base part, having an endless screw, H, on the lower part, and so arranged that the convolutions gear with the segmental cam G at a point above the center of the valve-journals, as

shown and described, torthepurpose set forth.

' by endless screws, as and for the purpose shown and described.

JOHN PENNYOOOK.
